I use camera flash too. About one foot away. I used to use the dual lamp setup, but its a pain in the butt...takes up too much space. Dani is right about the manual focus and high f-stop (for greater depth of field). You can see two light sources in my photos, but that is because my flash is a twin head. The difference between flash and screw in bulbs is a lot. Your cameras flash has a lot of output power. And its a clean light that you can get rid of the rest of the ambient light with. not saying you cannot use 2 light bulbs, but its not very handy for packing around. I suggest spending about a half hour experimenting with your camera and flash. Different settings, distances, etc. You should find a sweet spot somewhere along the line.
